I have a Netgear Orbi RBR20 system, and an external Trend Micro Home Network Security Firewall for content filtering. My kids use iPad and Kindel Fires, Chromebooks to access the internet. Chromebooks are mostly used for school work.

My problem is while the Netgear and Trend Micro device works well, playing around with different setups it always seems like no matter what the setup looks like when the Trean Micro box is unplugged I can still get on the internet, While this posses an issue when allowing people on the internet I am thinking of setting up a Fortigate 30E and setting up policies, my other option would be a Firewalla Blue but I worry about the same issue of disconnecting the Firewalla device. I Know I can connect the Netgear Orbi devices and use them as AP's but not exactly sure if this overkill or not.
